The Best Objective-C IDE is written in...
I'm working on a new mini-project, SeeingStars. This show real time poker odds for PokerStars. I'm writing it in Objective-C, as an opportunity to improve my rather basic Objective-C skills. I'm using AppCode, an Objective-C IDE from JetBrains which makes programming in Objective-C a more pleasant experience, compared to Apple's own, free Objective-C IDE Xcode.
And the ironic thing? AppCode is written in Java.
